Abstract
A motor vehicle drum brake () includes: two braking segments (A,B); an anchoring element () including two bearing surfaces (A,B) of two second ends () of the braking segments (A,B); a wheel cylinder () which, in a first 'simplex' operating mode, is suitable for transversally separating the adjacent first ends () of the segments (A,B); the anchoring element () including: a fixed body () wherein two sliding pistons (A,B) each carry a bearing surface (A,B); and elements () for separating the pistons (A,B) between an anchoring position wherein they abut against the body (), and a sliding position wherein the pistons (A,B) are separated to allow the sliding thereof during operation in so-called 'servo-dual' mode.
